Urgent help i finish period on 17/05 and 4 days after that i had sex. i take postinor 2 after sex which is 2 hours. is 4 days after period can get pregnant? and should i do pregnancy test?

It is possible to get pregnant 4 days after the end of your period. While it is less likely to conceive during this time, there is still a possibility of ovulation occurring earlier than expected or sperm surviving longer in the female reproductive tract. Taking Postinor 2 within 2 hours after having unprotected sex can significantly reduce the risk of pregnancy, but not 100% effective.
